All the Enfields are simple machines compared to the others mentioned above - only one cylinder for example. Can't get much simpler nor easier to work on. So that decides it for me, here in outer left field, where the nearest dealer is 1400 miles or so away.
I think my Machismo, with no electric starter, separate gear box, simple, easy to work on carb, beats even the UCE, for me, that is.
Now my new EV, when it is complete, will be even simpler and cheaper to own, though it does have three wheels.
Nice to like what you have and not be looking around all the time.
